Definitions

  • the seed tape should be dissolved very readily by water, preferably dissolved at the time of planting. This requires the tape to be made from a material which is quite readily water soluble, as against materials which merely disintegrate or materials which dissolve relatively slowly.
  • Water-soluble ethoxylated polymers preferably polyethylene oxide film, preferably having a thickness of one-half to four mils.
  • This material is remarkable in having both rapid solubility and considerable tensile strength when dry. Also, it is quite stable when stored dry.
  • a commercially available one-mil film, consisting essentially of polyethylene oxide, for example has a tensile modulus of 40,000 p.s.i. when dry, yet at 68 it will dissolve completely in water Within seconds and at 104 will dissolve completely in 60 seconds. The contents are released respectively within 14 and 7 seconds after the water is added.
  • a commercially available two-mil film consisting essentially of polyethylene oxide has a specific gravity of 1.2 and has an area factor of 11,300'square inches per pound, so that a half-inch tape gives about one-third of a mil per pound.
  • Its tensile strength is about 8,000 p.s.i. MD and about 1,400 to 2,000 p.s.i. TD.
  • Its elongation is 90% to MD and 600 to 700% TD.
  • Solubility is excellent, releasing contents in less than 7 seconds and dissolving completely within about 80 seconds, at 40 C. It is durable, is clear, and can be heat sealed in a fraction of a second at to 325 F. It can also be sealed by applying a little water and pressure. When protected from light, heat, and moisture it stores well for long periods and does not crack from cold until temperatures of about -70 C. are reached. It can be handled easily by machines, kept taut without risk of breakage, andyet can be dissolved at planting time by adding water to the soil.
  • the heat seal may be A second at 275 to 300 F. at 30 o 50 p.s.i. or /2 second at the same pressure at 235 250
  • the water seal is done by wetting the edges and then tressing them firmly together, or by moistening the enire tape before putting the seed on it and then folding he tape and pressing the edges firmly together.
  • the seed itself is preferably dried carefully to a moisure content no greater than that approved by govern-men- .al agencies for packaging in hermetically sealed packages )r containers.
  • sweet corn, perennial ryegrass, ipinach, and crimson clover are permitted a maximum of ;eed moisture of about 8%, with a 1% tolerance permissible so that this would means a maximum permissible of 9%.
  • Beets and chard are not to exceed a 7.5% moisture content.
  • Snap beans, lima beans, peas, carrots, and celery are not to exceed a. 7% moisture content.
  • Lettuce and tomato seeds are not to exceed a moisture content of 5.5%; cabbage, broccoli, cauliflower, collards, kale, turnips, rutabaga, kohlrabi, brussels sprouts, mustard, and radishes are not exceed a maximum of moisture content.
  • Pepper is limited to a moisture content of 4.5% and creeping red fescue seeds are limited to a maximum moisture of 3.0 percent. In all these, 1% tolerance is permitted.
  • Other seeds should be similarly dried within the permissible ranges, or where none has been prescribed, within corresponding dry ranges.
  • the dried seeds are preferably placed in a uniform attitude so that the radical and hypocotyl end are preferably on the same level, at least as for any seeds where this is feasible. It does not matter on the small round seeds, but it does matter on the long narrow or oblong seeds, which are capable of much greater difference in orientation. These are preferably placed with their lengthwise axis extending lengthwise of the tape.
  • the seed may, if desired, be pelletized prior to being placed on the tape, in a suitable medium conducive to superior germination or growth after germination or protection from fungi or pests.
  • the tape itself may contain fertilizer, hormones, or other materials advantageous for the purpose; it may also be tinted or colored to indicate seed type or other intelligence.
  • the tape may be twisted or spun into a twine-like strand, if desired, after the seed has been enveloped in it. Tubular enveloping material may also be used.
  • FIG. 1 is an enlarged view in perspective and in section of a seed tape imbedded in the ground prior to dissolution of the tape material by water.
  • FIG. 2 is a fragmentary view in perspective of a portion of a seed tape embodying the principles of the invention.
  • FIG. 3 is a fragmentary view of a portion of the tape showing the placement of the seeds prior to folding.
  • FIG. 4 shows an enlarged view of the seed tape of FIG. 2 seen at approximately right angleswith respect to FIG. 2 thereto and with the tape folded over and heat sealed.
  • FIG. 5 is a view of a speed tape like that of FIG. 2 twisted into a twine-like strand.
  • FIG. 6 is a view of a tubular seed containing envelope of the same type.
  • a seed tape 10 of polyethylene oxide film one-half to four mils thick (preferably 12 mils thick) is fed along a surface in any suitable manner, and seeds 11 are placed thereon by any means suitable to retaining their alignment. Preferably, long seeds are aligned longitudinally. N0 adhesive or other tacky material is needed.
  • the seed is placed closely adjacent the center line or a pre-fold line 12 and then the tape 10 is folded over along the line 12 to give the envelope-like tape 10 shown in FIG. 4.
  • the free edges 14 and 15 are water sealed or heat sealed together, and the seed tape 10' thus maintains its tensile strength.
  • the whole tape may be premoistened, or the edges only can be moistened.
  • the seed tape 10 when planted, is laid to the correct depth at 16, which determines the depth of the seed, is covered with soil, and is preferably watered soon thereafter. The water dissolves the tape 10 within a few moments, so that its traces cannot be found after a rather short interval of time, leaving the seed in the soil in proper condition for germination. Fertilizers, hormones, and other desirable materials are thereby deposited in the soil near the seed at an ideal location.
  • FIG. 5 shows a twine-like strand 20, made by twisting a tape 10 containing the seeds 11. Such a strand sometimes has strength advantages.
  • FIG. 6 shows a seed-containing tube 21 basically similar to the tape 10'.
  • the tape 10 need not be uniform in width, it may be wider where it includes large seeds and narrower between seeds.
  • the tape is of course made larger and preferably thicker, but it still envelops the plant material and it will still dissolve quite soon and with quite good results.
  • a plant propagating device comprising an elongated envelope consisting essentially of thin, readily watersoluble ethoxylated polymer and a series of regularly spaced apart plant propagating media enclosed in said envelope and retained in position therein by envelopment.
  • said envelope comprises a flat tape folded over said media and sealed to itself to provide the envelope.
  • a propagating material comprising a tape of thin, readily water-soluble polyethylene oxide folded over along its longitudinally extending mid-line to provide two layers and sealed to itself, and a series of regularly spaced apart and oriented plant propagating media in between the two layers so as to be enclosed thereby and retained by the envelopment.
  • a seed tape comprising a strip of readily watersoluble polyethylene oxide one-half to four mils thick with seeds disposed at regular intervals along approximately the center line of the tape, said tape being folded over along said center line and sealed to itself so as to enclose said seeds and maintain their spacing, said seed being dried to moisture levels permissible for hermetic sealing in containers.
  • a propagating material comprising a tape of thin, readily water-soluble polyethylene oxide folded over along its longitudinally extending mid-line to provide two layers and sealed to itself, and a series of regularly spaced apart seeds enveloped between the two layers and non-adhesively held thereby.
  • a seed tape comprising a strip consisting essentially of readily water-soluble polyethylene oxide one-half to four mils thick with seeds disposed at regular intervals along approximately the center line of the tape, said tape being folded over along said center line and sealed to itself and not adhered to the seeds so as to enclose said seeds and maintain their spacing, said seed being dried to moisture levels permissible for hermetic sealing in containers.
